Ear acupuncture, also known as auricular therapy, is based on the principles of Traditional Chinese Medicine. Auricular therapy is widely used for many conditions, including addiction treatment, mood disorders, obesity, pain, PTSD, and other conditions. This medical system emphasizes a holistic approach to medicine, an approach that treats the whole person. The ear is a microcosm of the human body. The acupuncture points found on the ear help to regulate the body's internal organs, structures, and functions.
